With that in mind, last week we began our series on the “Magic of Radio” with a discussion of some basic shortwave radio equipment, including general shortwave listening gear and weather radios. This week we present part two of our two-part series .
Gaye aka G2: This week we want to move on to the next level of the hobby so how about starting with an explanation of antennas.
George aka G1: Sure! Easy to understand and it only takes a few paragraphs to get the basics.
When it comes to antennas, there is generally only one number you need to remember – 468. Here’s why that number is important:
If you know what frequency your radio is tuned to, you can use the formula 468 divided by the frequency (f) in MHz to come out with a value telling you how long a ½ wavelength antenna should be.
